<u>the </u><u>given </u><u>expression</u><u> </u><u>can </u><u>be </u><u>solved </u><u>as </u><u>follows </u><u>~</u>

\frac{x}{13}  - 1 =  \frac{5x}{2}  +  \frac{1}{2}  \\

<u>taking </u><u>LCM </u><u>both </u><u>the </u><u>sides </u><u>,</u>

\frac{x - 13}{13}  =  \frac{5x + 1}{2}  \\

<u>on </u><u>cross </u><u>multiplying </u><u>,</u>

(x - 13)2 = (5x + 1)13 \\  \\ \implies \: 2x - 26 = 65x + 13

<u>let's</u><u> </u><u>now </u><u>gather </u><u>the </u><u>like </u><u>terms </u><u>at </u><u>either </u><u>sides </u><u>of </u><u>the </u><u>equation</u><u> </u><u>~</u>

65x - 2x =  - 26 - 13 \\  \\ \implies \: 63x =  - 39 \\  \\ \implies \: x =  \frac{\cancel{ - 39}}{\cancel{63}}

<u>on </u><u>simplifying </u><u>the </u><u>equation</u><u> </u><u>,</u>

\implies \frac{-13}{21}\\

Find the derivative of f(x) = -9/x at x = 6
Svet_ta [14]
F(x)=-9/x which is equal to:

f(x)=-9x^(-1)  So the power rule for differentiation is used...

Power rule:  f(x)=x^e, df/dx=ex^(e-1) so:

df/dx=-9(-1)x^(-1-1)

df/dx=9x^(-2)  or if you prefer...

df/dx=9/x^2

df/dx(6)=9/36=1/4

Need help with this please
FromTheMoon [43]

Answer: -2

Step-by-step explanation:

Slope=rise/run

In this case we rise up 4

And we run 2 to the left which makes it a negative

So in this case the slope is -4/2

Which can be simplified to -2

At 7:30 a.m., a bus left Town P for Town Q at a speed of 60 kilometers per hour. 15 minutes later, a car left Town Q and headed
marissa [1.9K]

Answer:

the bus took 4.5 hrs going 60 kph to get from town P to town Q

this means that the distance from town P to town Q is 270 km

side note-the car kph isn't shown and it got to town Q faster than the bus, so it must have gone at a faster speed. i didn't use the car to solve the problem, just the bus.

John is selling tickets to an event. Attendees can either buy a general admission ticket, x,
Masteriza [31]

John sold 18 general admission tickets and 11 VIP tickets.

Step-by-step explanation:

Given,

Cost of each general admission = $50

Cost of each VIP ticket = $55

Total tickets sold = 29

Total revenue generated = $1505

Let,

x represent the number of general admission tickets sold

y represent the number of VIP tickets.

x+y=29     Eqn 1

50x+55y=1505   Eqn 2

Multiplying Eqn 1 by 50

50(x+y=29)\\50x+50y=1450\ \ \ Eqn\ 3

Subtracting Eqn 3 from Eqn 2

(50x+55y)-(50x+50y)=1505-1450\\50x+55y-50x-50y=55\\5y=55

Dividing both sides by 5

\frac{5y}{5}=\frac{55}{5}\\y=11

Putting y=11 in Eqn 1

x+11=29\\x=19-11\\x=18

John sold 18 general admission tickets and 11 VIP tickets.
